The Forest Giants, or Ents, are the inhabitants of Forest Heart. A race of tree-like giants who hold high reverance to nature.
In the ancient past, the Forest Giants original home forest was razed by the Trow who were using the ancient trees as fuel to feed their great forges. Since cutting down a living tree was akin to murder to an Ent, they warned the Trow to stop but were ignored. The forest Giants fought against the Trow but were unable to stop the Trow and their iron weapons from destroying thier homeland. The Dire Marsh is what remained of their home.
In the end, the forest giants traveled far south, away from the Trow and eventually reached Forest Heart. To the present day, the Forest Giants have never forgiven the Trow for how they 'Poisoned the soul of iron'.
The Forest Giants aided the Light during the Great War, lending their great strength to combat the Dark and provide a defence against the Trow who had joined Balor. However, for reasons unkown they withdrew their support for thirteen years, causing the downfall of the Provinces. Maybe they withdrew to defend Forest Heart more directly but no one knows for sure. During the final year of the war, the Avataras Murgen and Cu Roi tried to persuade the Giants to help them just as Soulblighter fell upon them. After fending off Soulblighter, some of the Giant travelled with The Legion and proved instrumental in capturing a bridge to Balor's fortress.
